First, to find the measure of the interior angle, you have to find the su of all the angles:

1080 degrees

Then you take that and divide it by the number of sides on the polygon, so in this case, 8 sides, and divide the total, 1080 degrees, and divide it by 8:

1080/8= 135

And, to solve it the other way around, if the interior angle isnt the variable, you multiply the measure of the interior angle by the nuber of sides on the polygon:

135x8= 1080

Answer:

the MEAN for class a is 72.6

the MEAN for class b is 84.0

if you take these means and compare them, you can see that on average, class B performed better.

Match the y-coordinate with the given x-coordinate for the equation y = log2x.

Troyanec [42]

Logs are exponents so the log base 2 of 2 raised to the power n is just n.

$y = \log_2 x$

1. $\log_2 8 = \log_2 2^3 = 3 \quad$ nope, not -1

2. $\log_2 4 = \log_2 2^2 = 2 \quad$ nope, not 1

3. $\log_2 2 = 1 \quad$ nope, not 3

4. $\log_2 1 = \log_2 2^0 = 0 \quad$ YES, matches, CHOOSE ME!

5. $\log_2 \frac 1 2 = \log_2 2^{-1} = -1 \quad$ nope, not 2

Answer: choice 4
